What it means
A JHA takes one task and splits it into steps. For every step, the crew names the hazard and decides how to control it. That might be a guard, a different tool, a spotter or a stop point.
JHA and JSA are the same idea under two names. One company writes job hazard analysis, the next writes job safety analysis. The method doesn't change, only the label on the form.
The best JHAs come from the people doing the work. A foreman who has done the task a hundred times knows where it goes wrong.
Why it matters
A hazard nobody named is a hazard nobody controls. A JHA gets the crew to say what could go wrong before they're standing under it. It also leaves a record a lead can review when the same job comes back.
What it looks like on a site
- Pick the task, then break it into steps in the order the crew will do them.
- Write the hazard next to each step, such as a pinch point, overhead work or a hot surface.
- Write the control next to each hazard, and say who is responsible for it.
- Review the JHA with the whole crew before work starts and have everyone sign.
- Update it when the job changes, and keep it with the job records.
